Hi,
it seems that there is an issue with guest hang ups not only with Windows guests, as also reported here viewtopic.php?f=2&t=105026
I have Linux (XUbuntu 21.04) guest, which does not work on 6.1.32, but works fine on 6.1.30.
When starting w/ 6.1.32 on a MSI Notebook running Win10 Home, the box either locks up after showing the text login prompt (but before launching the X-Windows session) or (on a host machine Lenovo Thinkpad P17 Gen 2, running Win10Pro) the guest launches, but under heavy load the machine starts to perform very badly until locking up.
The attached log file is from the MSI system. I left the VM open in its stuck state for an hour or two, to see if it would recover. It didn't.
Do you see anything useful in the logs?

Re: Machine hangs with 6.1.32 (possible regression w/ Hyper-V?)Hi
The hangup issue with 6.1.32 is actually in the Windows host, not dependent on the guest OS.
Your log does not show the long time offset statistic that has been fingered as the 6.1.32 bug indicator. However, host OS Hyper-V is enabled, and your host just may not be able to run Virtualbox under it. See HMR3Init: Attempting fall back to NEM (Hyper-V is active).

Doubt that the issue with freezing VMs in 6.1.32 in 'turtle mode' is 100% connected to the "long time offset statistic" which has been found to have at least a significant correlation. By now we actually have tracked down the cause, and it's an issue with interrupt delivery. A true regression in 6.1.32 from optimizing some APIC handling code, losing one bit. Resulting in Windows Hypervisor doing what it is asked to do but not what is the right thing.

Please try the VirtualBox test build 6.1.35r140972 (or newer) and report back, including a VBox.log file from a complete VM run if possible.
